A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. ...

This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.

For example, ball mills use large media, normally 1/2" or larger, and run at a low (10–50) rpm. The other mills, such as sand, bead and horizontal, use smaller media from 0.3 mm to 2 mm, but run at a very high rpm (roughly 800–1,200). High-speed dispersers with no media run even faster rpm (1,200–1,800). Various types of attritors …
